Interventions

  • Exposure to source and message content — BEHAVIORAL
    Within each arm, participants will be exposed to two messages each of which are delivered by the same source (peer or professional) and have message content related to one of the 7C Constructs.

Study Details

The goal is to identify the most impactful strategies for capturing attention and enhancing effectiveness of vaccine promotion messages. This will be done using an online survey that employs remote eye-tracking and self report measures to evaluate response to sample vaccine promotion social media content in rural populations in New England. Participants will be randomly assigned into one of 14 conditions in a 2(source: expert vs. influencer) by 7 (themes: constructs from 7C Vaccine Framework) experiment and view sample messages and then answer questions about their attitudes and beliefs while being monitored for eye-tracking.
